The investigation of sensory perception in biological systems attempts to discover new methods for network analysis. Our focus is on thermoception and tactitian. The way our bodies perceive the environment begins with external receptors that trigger the sensory neurons which are connected to interneurons. These transmit signals to the central nervous system where they bifurcate. Some converge signals to motorneurons where output is sent to the skin, sweat glands, and muscles while others transcend into electric signals towards the parietal lobe. This is a general process that varies between different senses. The process of tactitian contains six ways the mind processes characteristics of a stimuli (weight, texture, temperature, shape, and volume) all depending upon physical response. An object’s temperature is perceived through static contact in one spot. The way in which the body perceives temperature of an object and ambient temperature are very different. The center core regulates temperature by maintaining an equilibrium between cold and hot gradients entering and exiting the body through circulation. Because the areas furthest away from the core contain the highest density of sensory neurons, failed negotiation through motoneurons is directed towards the extremities of the body. When internal temperatures are too cold, the channels governing flow experience vasoconstriction, shrinking in diameter to prevent heat loss. The opposite occurs when the body experiences a rise in temperature. The channels undergo vasodilation where they expand to release water molecules to project cool temperatures onto the periphery of the skin. Although, both tactile and thermoceptive perception are primarily influenced through the extreme points of the body, the resulting feedback differs between the two. Tactitian transcribes through a more psychological deliverance; thermoception, on the other hand, alters speed of flow in the circulatory system.

The current age of social technology, while allowing people to connect across massive distances, is limiting the personal one on one connection people have with their neighbors. The goal of this research is to combine the potential of tactition and thermoception with architecture to create spaces that stimulate face to face interaction between people in a public setting.

The system creates thermal gradients defined by inherent human temperature tolerances. Heat emitters in the floor and ceiling will partition spaces creating unobstructed views. Temperatures will range from 60-80 degrees Fahrenheit to accommodate differences in activity levels. Sectional gradients will be determined by potential body placement focusing on the extremities of the body. The concentration of temperature change will be at average height level. Program determines the deployment of this system. This will host spatial networks combined with suggestive pathways to invisibly emphasize conditions manifested by virtue of ambient conditions based on variative surroundings. The system will create a dialogue of dynamic stability between the environment and individual perception. Three levels of conduction (input, transference, and response) intertwined by a series of links will negotiate interchange between different sources occurring simultaneously at different speeds amongst communicative trajectories. Sequential communication is essential for responsive environmental conditions. A choreography tailered to space and technology will emerge to engage the senses as they are launched into unfamiliar territory. The application of Piezoelectric sensors in the floor and ceiling will measure direction and frequency of occupants as detectors activate heat radiation to calibrate speed of occupants, to generate a synchronization between program and activity.

Competition Winner for $100,000 House



This design was selected to be built when “East End representatives chose to work with elements of designs by two students -- David Evancho and Amelia Golini.” - Pratt Gateway Feb 09

The studio was approached by East End Builders to design a 1,000 sf house for under $100,000 in Ludlow, Vermont. The challenge was to keep the cost low on the home, while keeping the building architecturally interesting.

Streamlined design using tight zones and cores in the house was critical to keeping costs low. Smart choices on structure and material were also important in reducing the final price. Important to my design was the use of the Miracle Truss system that reduced the material needed for the walls of the home, and the elimination of a traditional foundation in favor of concrete sono tubes for a significant reduction in labor costs. Due to the dimensions of the Miracle Truss system, my design grew beyond the the 1,000 sf dimension (1,728), yet I was still able to keep the cost below $100 psf ($79.27).

Rome Center for Advanced Learning


The proposed Center for Advanced Learning and Research in Rome, is located on the Capitoline Hill. This site is possibly the most historically rich in the world. Adjacent to the site are historic buildings and monuments such as The Roman Forum, Michelangelo's Piazza di Campidoglio, the church of Santa Maria in Aracoeli, and Il Vitoriano, with Trajan's Market and the Colosseum nearby. Despite the history surrounding it, the site is currently only leftover space full of retaining walls. Looked at in another way the site is the neglected "mortar" between the “bricks” of the nearby monuments.

The project required many different types of major program including Auditorium, Museum, and Think Tank. The design attempts to recreate on a smaller scale, a collection of distinctly diverse buildings. This also creates the opportunity to solve the same problem that affects the current site. What to do with the “mortar space” between the buildings? Therefore it was imperative to design an interesting and useful circulation space between the major elements of program.
Another focus of the project was to utilize the existing retaining walls and materials of brick and travertine in conjunction with new materials like litracon (semitransparent glass infused concrete) in the design.
Programs used for this project include CAD, Rhino, and Illustrator.

Housing, DUMBO Brooklyn

The requirement for this project was to design urban housing in the DUMBO section of Brooklyn.
The challenge of designing housing in an urban landscape is trying to provide the comforts and luxury of living in the country while in a condensed environment.
To do this, the project must provide generous and private outdoor space, large amounts of natural light, and the ability for the user to modify and adjust their outdoor and indoor threshold.

Using a modular system that allows for different apartment types to "plug" into the building allows the owner to grow or shrink their space as needed. To make the outdoor space more private, many of the elements of the apartment protrude to limit views to the balcony from other apartments. The living rooms are double height with floor to ceiling windows. To control light and noise entering the apartment, louvers are integrated into the windows. The system of louvers can also be adjusted to create a sunshade for the balcony.
Programs used to produce this project include CAD, KeyCreator, and Illustrator.
